Effect of Pipeline elevation to internal corrosion using OLGA in either onshore nor offshore

What is it about?

Corrosion is caused by an electrochemical reaction between the material surface and the corrosion fluid. It becomes a problem that often occurs in Oil and Gas surface facilities, especially in pipelines. The result would affect the safety and economy. This problem is caused by many factors, for example, pH, flow regime, CO2 partial pressure, temperature, etc. Meanwhile, there is a factor corresponding to the elevation of the pipelines that caused the uneven surface that need to be analyzed, whether the elevation will affect internal corrosion. By using NORSOK and de Waard model that is available in Olga Simulation software by Schlumberger, the author makes a pipeline model design, so that the internal corrosion of the pipeline can be predicted. This paper would explain how the elevation of the pipeline effect corrosion by the experiment of 1˚, 2˚, 3˚, 4 ˚, and 5˚ of pipeline elevation to corrosion rate. Otherwise, the pipeline’s lifetime is used to evaluate the use of the pipeline after corroding. As a result, the elevation pipeline decreased corrosion significantly than horizontal pipeline, and to prevent high potential corrosion in the horizontal pipeline, the thickness of the pipeline should be re-design based on the evaluation result to optimize the use of the pipeline until the end of the contract

Why is it important?

This will help you to find, how elevation significantly effect to internal corrosion. so that the internal corrosion can be minimized.
